This prints the name of the working directory (Print Working Directory)

4. history : Ah! The history command

It lists all the previous commands you entered (stored in bash shell), in case you need to repeat any of them. How convenient!

5. whoami : Who are you, really?

It prints the effective user, ID as in you.

7. ifconfig : Interface configuration anyone?

View or configure network interface on your system with this command.

8. echo : An utterly basic command

It prints stuff anywhere you want (whether in a file or in a program or on the terminal).

  • Use echo [text] > [file name] to print the text in a new file.
  • Use echo [text] >> [file name] to print the text in an existing file.
  • Using echo [text] without a ‘>’ will automatically create a new file for the text.

9. cat : Short for ‘Concatenate’ (fancy word for linking things together)

View one file (or many), view what’s inside a file, link files together, or copy contents of one file to another. No wonder it is a widely used command in Linux.

10. Clear : Do we even need to explain this? It clears the terminal screen.

Quick quiz : Do you remember what the ‘ls’ command was for?

PART TWO: Manipulation Commands

11. mkdir : Create directory

If you want to create a directory under Desktop called folder1, open a terminal and type this:

12. cd : Change directory

It is used to change or switch the current working directory. Such a basic one man.

change directory

13. cp : Do you copy?

14. mv : Move it! Move files from one location to another using mv command.

15. rm : Want to remove something?

remove command

PART THREE: Reading Commands

16. more : Displaying stuff one page at a time!

F** scrolling through endless number of lines. Use this command to view the content of a file in a convenient manner. One screen at a time. (Think of Powerpoint versus Word doc).

Test this using the following command:
more /usr/share/wordlists/dirb/small.txt

display one page at a time

17. less : Similar to more, but better.

Other that showing the file contents one screen at a time, the less command also uses its brain by not opening the entire file at once.

Test this using the following command:
less /usr/share/wordlists/dirb/big.txt

less command

18. sort : View information in an arranged manner

Confused? Use sort command to view the content in a specific order.
Use -r switch, to sort the contents in reverse order.

PART FOUR: Editing Commands

19. vi : Short for visual editor

Use this text editor by tying vi filename. This editor has two modes (command and insert)

  • Enter insert mode by typing ‘i’ and exit by pressing Esc.
  • Exit vi by typing :wq’
vi filename

20. nano : Quite a simple editor.

A command line text editor, GNU Nano comes with most Linux distributions. You can compare it with GUI editors. Try it if you are not a fan of vi or emac.

21. leafpad : Simple, lightweight, easy-to-use editor

A GTK+ text editor, Leafpad is easily compiled, does not depend on many libraries, and is pretty quick to start up.
Command: leafpad /etc/passwd

PART FIVE: Permission Commands

Approaching the end of this blog post, let’s play with some permissions, shall we?

22. chmod : Control who can access your files.

There are flags (permissions) associated with files that decide who can access them and to what extent.
Use the chmod (change mode) command to change the modes of access as you wish. You can either restrict or open access to a file. Makes you feel powerful, doesn’t it?

r = Permission to read the file.
w = Permission to write (or delete) the file.
x = Permission to execute the file or search a directory.

chmod

23. chown : Like chmod, like chown.

Files in Linux have 3 major types of access permissions: User, group and other permissions. By default, when a file is created, the owner(user) is the user who created it and the owner(group) is that user’s current group.
With chown (change owner) you can control who can access a file and to what extent.

chown

That’s it for now. Hope you make good use of these commands. Now that you have learnt a lot about how to operate the terminal, don’t be a hoarder and share this information with your friends. What are your top 5 used commands? Tell us in the comment section.
